Customer Reviews
 I would like to thank you for all your efforts to choose the correct atomizer for our spray dryer,High speed drying. The surface area of Raw Material liquid increased a lot after atomization through nebulizer, 95%-98% of moisture will be evaporated in high temperature airflow in a flash, only needs seconds time.


I really don't know how to thank you, you are my angel, Thank you very much. Super Fine Pulverizing this one is faster than other same power machine and is easy to operate and repaired.

Blister Packaging Overview

Are you a fully-equipped pharmaceutical, food processing plant, or chemical factory? One of the equipments that you may consider adding to your ammunition is the blister sealing machine.

Do you want to know what a blister packaging machine is and why you should have it? Read this guide to the end. We will reveal to you everything that you should know about blister packaging.


What is a Blister Packing Machine?

Blister packing machines are special machines that are used as unit-dose packaging for tablets, capsules, etc. The device has a component of a bubble pack that may be a cavity or pocket made up of a formable film, usually a thermoformed plastic or cold-formed aluminum film. This usually features a lidding seal of aluminum foil.

In other words, this is an electromechanical machine that has both moving and stationary parts that aid in packaging and sealing products in pre-formed cavities.

The mechanical movements facilitate the formation of sized cavities on packaging material, filling, and sealing with appropriate materials.

Using different packaging materials and principles of forming, Blister Packs could also be divided into three types:aluminum/plastic (thermoforming) bubble pack, aluminum/aluminum (cold forming) bubble pack, and aluminum/plastic/aluminum bubble pack.


Types of Blister Sealing Machine

Based on their operation process, the blister packaging machine is divided into three distinct categories.

These are :

  • Roller type blister packaging machine
  • Roller plate blister packaging machine
  • Flat plate blister packaging machine

Let’s have a brief overview of these blister packaging machines:


Roller type blister machine:


The working rule of the roller blister packing machines is quite simple. The forming film is heated and softened by the heating device. The blister is then sucked by the negative vacuum pressure on the roller forming molding roller, and therefore the filling device fills the packaged object into the blister, then passes through the roller type.

The heat sealing device seals the single-sided adhesive-coated cover film on the surface of the blister material at an appropriate temperature and pressure and seals the packaged object within the blister.


Roller plate blister sealing machine


The roller plate type blister packaging machine is developed with the foundation of a roller type and flat type blister packaging machine. That is, a flat type molding device is employed for blow molding (positive pressure forming), and a roll type sealing device is sealed, and its blister packaging machine working principle is essentially the same.


Flat blister sealing machine


The working rule of the flat forming blister machine: The formed film is heated and softened by the flat heating device. The softened film is blown into a blister by using compressed gas within the flat forming device, and therefore the filling device fills the package into the blister.

Then, it’s sent to the flat sealing device, and therefore the cover film is sealed with the formed film under suitable temperature and pressure, then the batch number is printed, and thus the broken line is pressed by the typing imprinting device. Finally, the punching device is punched into a predetermined size product section.


Blister Machine Working Principle

Regardless of the type, the blister packaging machine process is almost the same.

In the above process, among machines, the most important difference is predicated on a blister forming device and the heat-sealing device. The blister forming is split into drum type and flat-plate type.

Flat-plate type of blister forming device generally performs better than the drum type. Heat-sealing is additionally divided into drum type and a flat-plate type.

Regarding the heat-sealing effect, the flat-plate type is better than the drum type, while the drum type has advantages in speed and reliability.

The above blister packaging process is often completed by manual operation, semi-automatic operation, or automatic operation. For large scale production volume of blister packaging, relatively fixed variety, and therefore the demand for safe and sanitary, it’s advisable to use an automatic packaging line for production.

Additionally, automatic blister packaging machines are often connected with automatic printer, manual inserting machine, boxing machine . for an automated blister packaging line, to save lots of labor and time.


Advantages :

If you are in food, drugs, or chemical industries, chances are you may not be sure whether to buy a blister packaging machine or not. To make things crystal clear, here are the top benefits of using a blister packaging machine:


  • Guarantees product integrity: At this point, you can tell that this blister packing is used for very sensitive applications. They include food and drug industries. Blister packs provide an air-tight seal to the products. They won’t be exposed to moisture nor air. In doing so, the end product will retain its quality.


  • Tamper proof: Lister packages cannot be interfered with by any external physical forces. This also goes a long way in preserving the integrity of the pills and capsules.


  • Cost-effective: Blister packaging can save you a significant amount of money, especially when you want to cut down on the cost of packing capsules and pills. It is cheaper than plastic packaging.


  • Accurate dosage: Since the pills and tablets are in their designated packages, maintaining the accuracy of the dosage won’t be a challenge in any way. It will be easy for one to keep track of the drug dosage.


  • Improves identification: As we have stated, labeling is one of the activities that are highlighted by the blister packing machine process. It ensures that the products are easily identified by their names among other information.
